I have never recycled it. Do u ?
Yessir, I never dispose of it. With a living soil, it should still be very alive when you are finished. There are a fair amount of guides on doing it and it is simple. Bottom line, add more amendments, let digestion of amendments get going to recharge the goodies, use and smile.
I have around 150-160 gallons of soil, and at any given time am only using about half of it. I have a 3x3 "soil box that holds right at 60 gallons of soil. After making a fresh batch or doing a "face lift" on all the soil, I'll just put the extra there. As I harvest plants, I let the pot sit for about a week. If it was a large plant I will feed the soil an enzyme feed to hurry digestion up some. After the roots die some, I just dump it in the soil box. I break up the soil, and rip w/e roots are left in to smaller pieces. Most times I'll just add a small amount of veg type amendments (crab,shrimp,kelp,alfalfa) mix and let it sit for ~1-2 weeks. For the amendments I only add about 1/4-1/2 of the original ratios. As you already know EWC kick ass, I add that from time to time to, but again just whenever I feel the soil can use it. Same with mushroom compost.
Another thing I do is if I have any extra teas, enzymes, experimental feeds that do well on the plants, I just feed it to my soil box. Sometimes I'll just make a molasses feed just for the soil, and not the plants. It's not anything I schedule either like the plants, sometimes it's twice a month, sometimes 3 times a week.
Some things that can be added to the soil to improve/sustain more microbial life are charged bio-char (don't buy this, make it, I can explain if needed), pumice stone, lava rocks, and about anything porous and organic. Bio-char in my opinion is the best for harboring microbial life. A piece the size of a [HASHTAG]#2[/HASHTAG] pencil eraser contains over a mile of pathways for the microbes to live in. It is extremely important that the bio-chat be charged though, otherwise it will actually deplete your soil until the bio-char is occupied/charged. Charged just means to already have a microbial population before use. You simple brew it with ewc tea, EZPZ.
Rice hulls are a great substitute for perlite, and a better "organic lifestyle choice". Although perlite is organic, the process of making it is not, and uses tons of fuel to produce. Rice hulls on the other hand are a by product of the rice industry, wrok GREAT for drainage/areation, do not float, and as the decompose they feed the soil with fresh humus on a regular basis. The humus also helps sustain healthy, and active soil. Also if you have a home brew beer store, it's silly cheap. I get them for $0.96 a lbs. I just redid about 40 gallons and only added 3lbs.
If you have any particular questions about reusing you soil feel free to ask man.
